NERLYNX vs TASIGNA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Neratinib is an irreversible pan-ErbB receptor tyrosine kinase inhibitor that inhibits EGFR, HER2, and HER4, leading to reduced downstream signaling and cell proliferation.
Nilotinib is a tyrosine kinase inhibitor that binds to and inhibits the activity of BCR-ABL, the constitutively activated fusion protein responsible for chronic myeloid leukemia (CML). It also inhibits other kinases including KIT, PDGFR, and DDR1.
NERLYNX (neratinib) 240 mg (6 tablets of 40 mg) orally once daily with food for a total duration of 1 year.
400 mg orally twice daily approximately every 12 hours. Administer on an empty stomach (no food for at least 2 hours before and 1 hour after dose). Swallow whole with water; do not crush or chew.

Terminal half-life approximately 7–17 days (mean ~9 days) after a 240 mg daily dose, supporting once-daily dosing. Steady state reached by ~4–6 weeks.
Terminal elimination half-life is approximately 90-120 hours, supporting once-daily dosing.
Primarily hepatic metabolism; 97% of dose recovered in feces (including unchanged drug and metabolites), <1% in urine as unchanged drug. Biliary excretion is a major route.
Primarily fecal (approximately 66-93% of the dose) as unchanged drug and metabolites; renal excretion is minimal (<5% of the dose).
